ADVERTISING DISPLAY-MACHINE.

Specification of Letters Patent.

Application filed August 31, 1914. Serial No. 859,275.

United States, have made Improvements in i-\ lvertising Display-l\/[achines, of which the following is a specification.

The invention relates to machines for automatically displaying and shifting pictures and like matter for advertising or amusement purposes, and in certain aspects thereof, the invention relates more particularly to machines for projecting such pic-- tures and for handling them in strip form. Objects and advantages of the inventionwill in part be set forth hereinafter and in part will be obvious herefrom.

The invention consists in the novel parts,

-constru :tions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings herein referred to and constituting apart hereof, illustrate one embodin'ient of the invention, and together with the description, serve to explain the principles thereof.

.01 the drawings:

Figure 1 is a side elevation of a machine constructed in accordance with the principles of the invention;

Fig. 2 is a side elevation showing the opposite side from Fig. 1;

Fig. 3 is an end elevation looking at Fig. 1 from the right,

Fig. 4 is a fragmentary detail of the intern'iittent feed for the film strip;

Fig. 5 is a fragmentary view corresponding to Fig. 4, looking thereat from the right, and showing the machine frame in section on the line A- B; and

Fig. 6 is a fragmentary View taken in section on the line CD of Fig. 5.

Referring by way of example to the .ac companying drawings, illustrating oneernbodiment of the invention means are provided for intermittently feeding the" film strip in either direction, and in connection therewith means for smoothing and holding the film while it is being shown or projected. In accordance with one feature of the invention said means operate automatically 'and in connection therewith are means which automatically reverse the direction of travel of the film, the successive pictures or like matter on the film being shown or projected during the intermittent travel in both directions.

In the embodied form of such means, a reel 1 for winding and unwinding the film strip is provided. Said reel 1 is mounted upon a shaft 3, which shaft is carried in a suitable hearing or journal 2 in the frame 4 of the machine. The reel 1 is provided with flanges 5 and 6 for holding and alining the film strip upon the reel. Suitable devices for permitting the insertion and withdrawal of the reel 1 with respect to the shaft 3 are provided, and also means for causing the reel to turn with the shaft. In the embodied form, a pivoted locking lever 7 is mounted in the end of the shaft 3 and a coil spring 8, operating between suitable washers, holds the reel in position. A suitable spline or other device may be utilized to cause reel 1 and shaft 3 to rotate together.

At the other end of the machine there is provided a reel 15, having flanges 16 and 17. The reel 15 is removably mounted upon a shaft 18, which shaft is journaled in a bearing 19 in the machine frame 4. A pivoted locking lever 20 and a spring 21, similar to the lever 7 and spring 8 permit the insertion and withdrawal of the reel 15 with respect to the shaft'18, and suitable engaging means for causing reel 15 to turnowith 29. The pulley 29 is mounted upon a worm shaft 30,.said worm shaft being journaled at- 31 and 32 upon the machine frame. Meshing with the worm shaft 30 is a worm wheel. 33 fixed upon a shaft 34, said shaft being journaled at 35 upon the frame. Fixed also to the shaft 34 is a sprocket wheel 36. Passing over sprocket wheel 36 and driven thereby is a sprocket chain 37, said sprocket chain also passing oversprocket wheels 38, 39 and 40. Wheel 38- is shown provided with a tension adjustin device 54.

Fixed to-the sprocket chain 37 1s a pin 41, said pinprojecting laterally therefrom into the path of a star wheel or radially slotted rotatable disk 42, mounted to rotate with the shaft 43. The disk 42 is shown with Patented Sept. 3, 1918.

four radial slots 53 therein. The shaft 43 is journaled intermediately in the machine frame 4 and its ends are likewise ournaled in brackets 44 and 45 supported from the machine frame. Fixed upon the shaft 43 are disks 46 and 47 provided, respectively, with sprocket teeth 48 and 49, wh ch sprocket teeth'are adapted to engage with holes y in the side edges of the film strip m to give a positive and accurate feed or advancement to the strip.

Means are provided for movlng the film carrying reels 1 and 15 in harmony with the movement of the sprocket disks 46 and 47 to wind up the strip as fed by the sprocket disks, and dependent upon the direction 1n which the film strip is being fed. As embodied, there is mounted on the shaft 43 to rotate therewith a pulley 55, carrying a belt 56, which belt passes over a pulley 57 upon passing also over a pulley 67 mounted upon the end of shaft 18. Pulley 67 is connected to shaft 18 by a one way clutch mechanism 68. Thus the pulley 67 acts to rotate the shaft 18 in one direction, while the pulley rotates idly in the other direction without rotating the shaft. The pulleys 67 and 57 are arranged to clutch their respective shafts in opposite directions, so that when the shaft 43 and the sprocketed disks 46 and 47 rotate in one direction, either the reel 1 or the reel 15, depending upon which reel is winding up, will be positivelyrotated to the same amount or degree as the movement of the film strip .70, while the paying off reel, whether the reel 1 or the reel 15, will rotate freely to. give off the necessary amount of the film strip 00. The driving pulleys on shaft 43 are somewhat larger in diameter than the driven pulleys on shafts 1 and 18, to. insure the reeling of the entire amount of film fed by the sprocketed disks 46 and 47.

Means are provided by the invention for accurately registering or positioning the film strip after each intermittent feed, thereof, so that the successive pictures may of engagement with the respective notches 72, the'corresponding beveled shape of the notch and detent giving a'very accurate positioning or registration of the film strip. The detent 73 is shown 1n engaging position with a notch 72 in dotted lines in Fig. 6 and automatically reversing the intermittent feed of the film strip at the end of its travel.

In the embodied form of such means, the film strip at is detachably attached to a short sheet or strip 75, the other end of the strip 75 being attached to the reel 1, at the top end. A similar arrangement is provided in connection with the reel 15 at the bottom end. Fixed to the strip 75 in proper position is a hook 76, which hook is adapted to fit into a recess 77 in the reel 1 when wound thereon. Pivotally mounted on the frame of the machine is a lever 78, having in one end thereof a pin 79, which pin projects into the path of the hook 76. The other end ofthe lever 78 is pivotally connected to a rod 80, the other end of the rod 80 being pivotally connected to one end of a lever 81. The lever 81 is pivoted on the machine frame and is similar to the lever 78. Lever 81 has a pin 82 projecting into the path of the corresponding hook 76 of the strip 75 which is fixed to the lower reel '15. .Carried upon the rod 80 is a pin 83, which pin is embraced by the slotted end of a lever 84. The lever 84 is connected to a double pole switch 85, which switch is in the circuit 86 of the motor 25.

Thus when the film m has been run ofi? or exhausted from one reel or in one direction, the switch 84 is thrown-and the motor 25 is reversed and then rotates or drives the machine in the opposite direction, thereby feeding the film intermittently in the opposite direction. In Fig. 1, the lever 78 in the full line position is adapted to be engaged by the hook 76 of the reel 1 and to be moved thereby into the dotted line position, thus reversing the polarity of the switch 85. The lever 81, by means of the rod 80.is at the same time movedto the dotted line position.

It is then adapted to be engaged by the book 76 of the reel 15, when the film strip has reached the otherend of its travel.

Means are provided by the invention for smoothing and holding firmlythe film strip a: at the point of exposure or projection while the p cture is being exposed or projected and for releasing the film strip while it is being fed. In the embodied form of such means, there are provided two transparent plates 90 and 91 preferably of glass and located upon either side ofthe film stri a:

at the place of exposure or projection.

Therods92; and 94 are slidably mounted in cross" -b'ars96 carried upon the machine frame, andep'iled springs 97 act to press the plate9 aga nst the plate 90. The rods 93 and9 arefs'imilarly mounted in'cross bars 98, andare, similarly acted upon by springs 99. Thus, as embodied, the plate 91 is continuously spring impelled toward the plate 90, and means are provided for retracting it, against the action of the springs to release the film strip 00 during its feeding movement. In the embodied form'of such means, there is provided upon the rod 93 a lug 100, and upon rod 95 is a corresponding lug 101. The lug 100 is in the path of an arm 102 fixed to a shaft 103, said shaft being mounted in the machine frame. The lug 101 on rod 95 is in the path ofan arm 104 like wise fixed to the shaft 103. Fixed on the end of shaft 103 is an arm 122.

The rod 92 is provided with a lug 105,

which lug is in the ath of an arm 106, fixed to a shaft 107, which shaft is journaled in the machine frame. The rod 94 is provided with a lug 108 in the path of an arm 109, said arm being likewise fixed to the shaft 107. The shaft 107 has an arm 1:10 fixed to the end thereof. Slidably mounted upon the frame 4 is a plate 112, said plate being held in position by guiding members 113 and 114 passing respectively through slots 115 and 116 in the plate 112. The plate 112 is impelled in an upward direction by the springs 117 and 118. The plate 112 is connected by a pivoted link 119 to the arm 122 on shaft 103. The arm 110 on shaft 107 has in the end thereof a pin 120 engaging with a pin or lug 121fixed in the sliding plate 112. Thus the shafts 104 and 107 are rocked in conformity to the sliding move-- ment of the plate 112, and the glass plate 91 is accordingly successively and automatically moved toward or away from the glass plate 90. I

The embodied form of moving andcontrolling means for the sliding plate .112 comprises two inclined cams 125 and 126 at either end of the enlarged or T-shaped head ofthe slide 112 together with a level or smooth bearing surface 127 between the cams 125 and 126 (Figs. 2, 4 and 5). Thus when the pin 41 travels to the right along the bottom reach of the sprocket chain in Fig. 1,

it will engage the cam 125, and move the sliding plate 112 downwardly against the springs 117 and 118, and thus rock shafts 103 and 107 to move plate 91 away from plate 90. So long as the pin 41 travels along the straight face 127 on the plate 112, said plate is held in the downward position and the plate 91 is held retracted from the plate 90. When the pin 41 reaches the cam 126 (Fig. 1), the plate'112 slides upwardly, and the shafts 103 and 107 rock to permit the plate 91 under the action of springs 97 and 99 to move forward and press the film strip against the plate 90.

The detent and registering device 73, heretofore referred to, is mounted on the slide 112. When slide 112 is in the lower position, the detent and registering device 73 is retracted and when slide 112 is in the upper position, the member 73 firmly holds and registers centers the film strip.

It will be understood that after the plate 112 has been slid downwardly and the plate 91 has been drawn away'from the plate 90, pin 41 enters one of the radial slots 53 in the slotted disk 42, thus rotating the sprocketed disks 46 and 47 and therewith either the reel 1 or the reel 15 thereby giving a feeding movement I or travel to the film strip 00. When the pin 41 passes'out of. the radial slot 53. inthe disk 42 (which in the considered instance would be at the right in Fig. 2), the feeding movement of the film strip would be stopped, and also by reason of the pin 41 passing the cam 126, plate 122 movesupwardly and the plate 91 would move backwardly against the film just after the film has come to rest.

As embodied, the invention provides projecting means for projecting the picture upon a screen, and in connection therewith an automatically operating shutter mechanism for shutting off the light during the feed of the film. As embodied, a set of con densing lenses 130 are provided, the plate 90 being conveniently mounted at the front of the carrier 131 for the condensing lenses. An aperture plate may be provided back of plate 9 1. Projecting lenses of suitable form may be provided, and a, lens tube 132. for lenses is shown. In front of the lens tube 132 is a shutter disk 133, pivotally mounted at 134 upon a forward projection of the machine frame. A counter weight 135, which may be adjustable along its supporting arm 136 is provided. Projectingthrough a slot 137 in the arm 136 is a lever 138, which lever is pivotally supported at 139 upon the machine frame. The other end of the lever 138 projects into the path of the sliding plate 112, or some part connected therewith. The shutter 133 is thus swung machine frame. The sets of rollers 140 and 141 are flanged and grooved to cooperate with the disks 46 and 47 and having their grooves located over the sprocket teeth 48 and 49 .in a well-known manner. Below said rolls, a pair of rolls 144 are pivotally mounted on.

a spring-pressed frame 150 swung on the lower part of the swinging frame 142 and cooperates with a pair of rolls 145 mounted upon the machine frame to preserve the film strip m in alinement with the opening between the plates 90 and 91, and to cause the film strip to move free and not adhere to plate 90 just prior to the feeding movement. Below the plates 90 and 91 a pair of rollers 146 are mounted on a swinging spring pressed frame 147 mounted at 148- on the machine frame. The rollers 146 cooper-,- ate with a pair of rollers 149, mounted on the machine frame. The said arrangement of the rollers 144, 145 and 146 and 149 whereby they move the film strip free from stationary transparent plate 90 just prior to the feeding movement is shown in Fig. 1, the rollers being mounted or centered so that the line of feed of the film is a slight- 'distance in front of plate 90, plate 91 moving the film slightly backwardly just before it is pressed smooth between the two plates. The rollers 146 and 149 cooperate to move the film strip away from plate 90 and serve to aline the film strip and to direct itto the reel 15. I

From all the foregoing it will be understood that a machine has been provided which embodies and realizes the object of invention and the advantages herein set forth, together with other objects and advantages. It will be understood also that in its broader aspects the invention is not limited to the precise form of mechanism shown and described, but that departures may be made therefrom within the scope of the accompanying claims, without departin from the principles of the invention and without sacrificing its chief advantages.
